No. Although both 5252 and (−5)2(−5)2 are 2525, the radical symbol implies only a nonnegative root, the principal square root. The principal square root of 25 is √25=525=5.Example: Evaluating Square Roots Evaluate each expression. √100100 √√1616 √25+14425+144 √49−√8149...
The integration which makes the effect of changing the function then integration is called integration by substitution. For example, a linear substitution ofu=ax+b,where u is the substitution. The preliminaries we us...
